UNITE 2' STATES PATENT FIQ IRVING I. WILD, OF RED BANK, NEW JERSEY,ASSIG-NOR OEONE-HALF TO THEODORE S. CLARK, OF BROOKLYN, NEW YORK.

PRINTING COLOR ATTACHMENT.

To all whom it may concern:

Be it known that I, IRVING L. WILD, a citizen of the United States,residing at Red Bank, in the county of Monmouth and State of New Jersey,have invented a certain new and useful Improvement in Printing ColorAttachments, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings.

This invention relates to color printing attachments for presses and hasfor its 0-bjcct to provide a construction which may be conveniently andeconomically applied to presses, especially of the Gordon type and whichwill enable ink of different colors to be applied to the type.

In carrying out my invention, I employ a plurality of strips, which maybe formed as part of a stencil yieldingly supported above the inkingdisk or platen, said stencil hav ing slits so arranged as to permit therollers operating thereover to receive ink through the slits, certain ofthe slits and the corresponding roller being appropriated to one colorof ink while certain other slits and the corresponding roller areappropriated to ink of another color.

Generally speaking, the invention may be further denned as consisting ofthe combinations of elements set forth in the claims hereto annexed andillustrated, in one exempliiication, in the drawings forming a parthereof, wherein Figure 1 represents a perspective view of a Gordon presshaving my invention applied thereto; Fig. 2 represents a plan view ofthe inking disk or platen and the frame which supports the stencil; Fig.3 represents a sectional view taken through the central portion of thedisk and frame; Fig. 4, a diagrammatic plan view of the rollers, diskand stencil. Fig. 5 is a plan view of a form, showing the arrangement ofthe lines of type therein, whereby they may be inked in accordance withmy invention, and Fig. 6 is an enlarged detail, partly in elevation andpartly in section, of one of the inking rollers.

Describing the parts by reference characters, 1 represents the upperportion of a press Specification of Letters Patent.

of the Gordon type, the same having the ordinary rotatable inking diskor plate 2, roller tracks 3 and piv0tally supported roller arms 4:.

5 denotes a standard having at its upper end a journal 6 for the stud 7carried by the inking disk or platen 2. This inking disk is providedwith the ordinary ratchet 8, by means of which and the pawl 9,step-bystep movement is imparted to the inking disk in a manner wellknown in the art.

The above mentioned parts are of ordinary construction and need nodetailed de scription.

The inking attachment which I provide consists generally of a stencilsupported above the disk, the disk having ink applied thereto inconcentric circular bands and the stencil having apertures, spaced inaccordance with the arrangement of the lines of type in the form, abovethe portions of the platen or disk which carry the different coloredinks, with rollers having projections that register only with the slitsin the stencil corresponding to the desired color of ink.

10 denotes a frame having a short sleeve 11 by means of which and screws12 the frame may be supported by the journal 6. This frame is providedwith a recess 13 which receives the inking disk 2. At its upper end, theframe is provided with a plurality of apertured lugs lt through whichthere extend bolts 15. The lower ends of these bolts are threaded into across bar 16. Each bolt has applied thereto, between a lug 14 and itshead 16, a spiral spring 18, by means of which the cross bar isyieldingly supported by the bolts.

19 denotes astencil, which may be formed of any suitable material, asheavy stencil paper. This stencil may be secured at its upperend to thecross bar 16 by means of slits 20 adapted to be applied to pins 21carried by the bar. The lower end of the stencil may be secured, as bymeans of pins 22, to the lower edge of the frame 10. The parts are soarranged that, as the inking disk revolves, the stencil will be out ofcontact therewith, as indicated in Fig. 3.

The manner of using the stencil with two colors of ink, say black andred, is as fol- I I lows :'-S uppose the inking disk to be twenty inchesin diameter.

suitable number of slits 23 will be cut in that portion of the stencilwhich is above the outer circle of the disk and a suitable number ofslits 24., alining with thespaces between the slits 23, will be formedin the stencil above the central portion of the disk.

that'is to say,across that portion of the disk which receives the blackink.

In this form,the lines of type 27 extend up and down, or in the same attachment, Iemploy a special form of cogeneral construction and comprise each aplurality of, roller sections mounted on a mandrel, sald roller sectionsbelng separated by recesses: and the sections being adapted to receiveink through the slits in the stencil.

"Two of these rollers are shown at28 and 29 1 respectively, and thelatter roller is shown in detail in Fig. 6. With the arrangementofcolors selected for illustration herein,the

' roller 29 may be referredto as the red ink roller sections 31, 31 31and 32.

Theroller 28 is made upinlike manner of projecting portions 33 and reduced portions 34, the

projections and recesses of one roller being arranged complementarilywith respect to the projectlons and, recesses on the other roll. Ifdesired, three rollers altogether may be used, as shown, two ofwhich'will necessarily be of identical construction.

distribute on the projections of the rollers 28 and 29 the ink which maybe taken from l the exposed portions of the disk.

In operation, the rollers 28 and 29 are moved along the tracks 3 andover the inkmg dlskin the usual manner. The spring support for thestencil enablesthe latter to be pressed downwardly against the diskasthe rollers'move over the same, and the pro- With the rollers 28 and29,there maybe, employed small distributing rollers 35, whichserve tovtending from the slits 23, enables. the roller 29, after receiving inkthrough the slits 23 to be'moved across the disk without bring ing itsprojections into contact with the central portion of the disk, whichportion carries ink ofan-other color from that taken through the slits23. Furthermore, the strips 25 serve to distribute the ink on theprojecting portions of the roller 29. As no strips are providedcorresponding to the slits 24', it will probably be desirable to use twoinking rollers 28 to insure proper supply of ink to the form. A furtherdistribution ofthe ink on the projecting portions of the rollers issecured by the distributing rollers 35.

:By the construction disclosed, the strips 25 are pressed upon the.surface of the disk only at the time when the disk is not rotated.Furthermore, the inking of the under surfaces of these strips by thedisk does not affect the color of the ink which may be distributed onthe upper surfaces thereof. It will be understood that the depth of therecesses formed bet-ween the projections of a roller will be greaterthan the thickness of the stencil or the strips 25, so that there willbe no rubbing of the upper surface of the stencil or the strips by therecessed portions 7 of the rollers.

By reference to Fig. 6, it will be seen that the individual projections31 are built up of one or more independent sections 31, 31 The sections31 are of the width of a line of type while the sections 31 are amultiple of such width. By this construction, I

am enabled to build up very quickly rolls for use in color printing,which rolls will be provided with surfaces of sufiicient length toreceive ink through slits of varying width, the variation in the widthof the slits corresponding to the matter to be printed. For instance,the left hand projection of the roller shown in Fig. 6 may comprise asection 3l which is of the width of a single line of type and asection'31 which is of the width of three lines of type, the whole projectionbeing equal to the width of four lines o of type. The projections 31 maybe of the width of a single line of type, while the projection 31 at theright-hand end of the roller is of the same width as that at the left.The roller 28 may be built up in like manner to form projectionscomplementary to those on the roller 29. The

, construction as a whole provides a particularly economincal meanswhereby a plurality of colors may be applied to the type locked in theform, maintaining the various colors separate from each other andeifeetively distributing the ink on the respective rollers. While forthe purposes of illustration two colors of ink are selected, it will beap parent that more than two colors may be used and that these colorsmay be arranged differently on the printing disk than described herein.
